TOOL-HOLDER.

Specification of Letters Patent.

Patented May 15, 1917..

Application filed December 14, 1916. Serial No. 136,912.

To all whom it may concern.

Be it known that I, OSCAR T. ANDERSON, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Tool-Holders, of Which the following is a specification.

My invention relates to improvements in tool-holders, and the object of my improve ment is to supply a holding device for lathetools and the like, provided with adjustable means for clamping the tool therein.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is a top plan of the device and Fig. 2 is a side elevation thereof in partial section.

Similar numerals of reference denote corresponding parts throughout the several views.

My improved tool-holder comprises a block 1 having an enlarged forward end 2, the latter having a socket 8 opening to the front and inclined downwardly to the rear. The block part 2 has a cylindrical socket 7 in one side to receive a cylindrical rock-body 4 having an outwardly-extending hexagonal head 6.

The numeral 11 denotes a lathe-tool seated in the socket 8 to project forwardly there from, and a wedge 9 is mounted in said socket to fit between the inclined upper wall of the latter and the up per surface of said tool.

The rock-body 4 has a number of pinion teeth 5 meshing with like teeth formed in the upper part of said wedge, whereby, when a wrench is applied to the hexagonal part 6 to rock the rock-body 4, the wedge 9 may be longitudinally shifted to accommodate itself to the tool 11 to clamp the latter in an adjusted position. The wedge 9 has a long bearing on the tool 11, and therefore, holds it firmly in its seat. The rock-body 4C is quickly actuated to shift the wedge 9, and works positively in adjusting the wedge to hold the tool in the simplest manner.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A tool-holder having a longitudinal tool receiving channel and a socket at right angles to said channel communicating with same, a rock-body in said socket having a number of gearteeth, and a wedge mounted in said channel having a number of gear teeth in mesh with the teeth on said rockbody and adapted to adjustably clamp a tool between itself and the inner wall of the channel.

2. A tool-holder having an inclined tool receiving channel opening at one end and a lateral socket at right angles to said channel communicating therewith'and spaced away from the end of the holder, a rock-body in said socket having an outwardly extending projection and having a number of gearteeth extending into said channel, and a body seated movably in said channel and adapted to clamp a tool between itself and the inner wall of the channel, said body having a number of gear-teeth in mesh with the gear-teeth on said rock-body.

Signed at Waterloo, Iowa, this 11th day of Dec. 1916.

OSCAR T. ANDERSON.
